There is more power to be found at 10 psi and tuning. You are running way beyond what and Pump gas can handle.

 

I'm gonna agree ... 15psi and you should be making some more power. I think something's wrong there.

Have you thought about tuning it yourself?

Obviously so since you got screen shots with HPTuners.

 

agreed

 

I agree as well. Torque numbers are pretty awesome though. I changed the plugs last night and number 5 was fouled, like it hadn't been firing properly, that could account for some reasons. I am going to get a 3" pulley from Allen and have him help me with a tune, then i'll tweak it on the dyno. I'l also like to get some numbers running 110 octane and the smaller pulley. Would be good for some nice numbers.

 

I forgot ... this is going through a 6 speed too. That's way off. You should be up around 500, or a lot closer to it than that.

 

That's what I was saying in another thread, the torque numbers are really high, but HP is low. Typically in these trucks the HP and torque numbers are pretty close.

Detonation is bad.
